PC Series 300

Industry standard ISA/PCI architecture, first IBM machines with USB. Processors ranged from the 486DX2-50, 486SX-25, 486DX4-100 to the Pentium 200 and in case of the Models 360 and 365 the Pentium Pro. 486 models had a selectable bus architecture (SelectaBus) through a replaceable riser-card, offering the choice of either VESA Local Bus/ISA or PCI/ISA. Within the 300 series the following models appeared:

PC 330

An IBM Personal Computer 330 (6577-9BT)

Its last sub-model used the Pentium P54C processor clocked at 100, 133, 166, or 200 MHz. It had, depending on the sub-model, up to 4 ISA and/or 3 PCI expansion slots and four (2 external 5.25", 1 external and 1 internal 3.5") drive bays. It had in its latest version, the 6577, one DIMM-168 and 4 SIMM-72 memory slots, and featured an IBM SurePath BIOS. This PC has 2 USB 1.0 slots in the back. The latest version of Windows which can be installed on this PC is Windows XP, though Windows 2000 and Windows ME are optimal choices.

The DIMM-168 memory slot takes 5V EDO DRAM and is incompatible with the more commonly used 3.3V SDRAM. The slot looks the same at first glance, but the keying is different. Trying to force a 3.3V SDRAM module into the slot could damage both it and the memory module.

Submodels were:

PC 340

An IBM PC 340.

The PC 340, introduced in 1996,^[1] was a budget model. It used the Pentium processor clocked at 100, 133 or 166 MHz. It had 4 ISA and 3 PCI expansion slots and four (2 external 5.25 inch, 1 external and 1 internal 3.5 inch) drive bays. It had 4 SIMM-72 RAM slots, and featured an IBM SurePath BIOS.

The submodels were:

• PC 300 Series Model 340 (Model 6560-1xx)
• PC 300 Series Model 340 (Model 6560-4xx)
• PC 300 Series Model 340 (Model 6560-5xx)
• PC 300 Series Model 340 (Model 6560-6xx)
• PC 300 Series Model 340 (Model 6560-7xx)

PC Series 700

These systems used the Intel Pentium processor with clock frequencies of 75, 90, 100, 133 and 166 MHz. Initial systems had selectable bus architecture (SelectaBus) through a replaceable riser-card. Options were either PCI/ISA or PCI/MCA. The ISA or MCA bus would be connected to the PCI bus using a PCI to ISA/MCA bridge. The advantage of this is that even operating systems without MCA support worked on the system, as long as the MCA portion was not required.

Two form-factors were available, the 3x3 (3 slot, 3 bay) PC 730 and the larger 5x5 (5 slot, 5 bay) PC 750.

PC Series 3000

This series was introduced in April 1996 in Canada only. It has a Pentium processor clocked at speeds ranging from 100 to 166 MHz and was shipped with a Mwave modem/sound card.

PC 300PL

The 300PL used three models of processors during its lifetime, the Pentium MMX, Pentium II and Pentium III. Models using the Pentium MMX came in speeds of 166, 200 and 233 MHz; models using the Pentium II came in speeds of 266, 300, 333, 350, 400 or 450 MHz; and models using the Pentium III came in speeds of 450, 500, 533, 550, 600, 667, 733, 800 or 866 MHz. The 300PL usually shipped with a hard drive with a capacity ranging from 2 GB to 20 GB, a CD-ROM drive, and a floppy drive. In some models, an IBM EtherJet 10/100 Ethernet network adapter is also included. The IBM 300PL came either in a tower or a desktop form-factor.

Four different types of form-factors exist:

• Three PCI slots, no AGP; it also has an extra bay for a CD or DVD drive (desktop)
• Three PCI slots and one AGP; it also an extra bay for a CD or DVD drive (desktop)
• Four PCI slots and one AGP; it also has an extra bay for a CD or DVD drive (desktop)
• Six PCI slots and one AGP; it also has two extra bays for a CD or DVD drive (tower)

PC 300GL

The PC 300GL used the Celeron, Pentium I, Pentium II and Pentium III throughout its lifetime. Celeron-based models had processors clocked at 333, 366, 433, 466, 500 or 533 MHz; Pentium I models had processors clocked at 133, or 166 MHz; Pentium II-based models had processors clocked at 350, 400, 450 MHz; and Pentium III-based models had processors clocked at 450, 500, 533, 550, 600, 667, 733, 800 or 866 MHz.

These systems were packaged in two case form-factors, desktop and micro-tower. There were two variants of the desktop case, one with two expansion slots and one with four. Both variants had four drive bays. The micro-tower case had four expansion slots and four drive bays.

PC 300XL

The PC 300XL uses the Pentium MMX clocked at 233 MHz, or the Pentium II clocked at 233, 266 or 300 MHz.^[2] It features integrated 10/100 Ethernet.
